The electric circuit to electric inotor, not shown, is made through the hour and minute hands of a clock at 8586. 1.1.5

The operation of my device is as follows: When the electric circuit to the motor is made at twelve oclock, noon. by the hour and minute hands of a clock by contacts 85-86, the motor starts operating governor 70 by belt 5 said governor drawing out block 76, the same engaging the outer notch 78 of arm 77, the same being carried over to engagement by arm 11; this prevents the operation of the time shaft until the motor shaft is stopped by the passing of the minute hand of a clock past electric contact 86. The governor then releases block 76, arm 77 is then drawn back by spring 7 7, at the same time turning time shaft 81 one quarter turn around by coming in contact with ratchet wheel 80; this movement partially releases arm 54. 'At midnight, when the electric circuit to the motor is made, arm 77 is advanced by revolving arm 11 to engagement with ratchet wheel 80 in advance of block 76; arm 77 is then drawn back by spring 77, turning time shaft 81 one quarter turn around, releasing arm 54, when said arm is carried over to cam 9 by spring 56; said arm 54 is raised upward by cam 9 connecting gear 13 with gear 14, and arm 54 with clutch by spring 57 engaging with worm gear 10, which connects clutch 2021, thereby turning sprocket wheel 23 and chain 24, the same turning h sprocket wheel 25 and paper roller 28, thus drawing down calendar paper the required distance by measure roller 33 until trip arm 47 comes in contact with trip lever 48, when arm 54 drops down, disengaging clutch 20-21 and gear 13, when calendar paper roller 28 stops, leaving calendar paper in place as shown in Fig. 10.
